Mattison Grinding

Mattison Grinder

Mattison Grinding machines can handle extremely long parts, up to 220″ long. Precision Grinding maintains several Mattison Vertical and Horizontal Spindle Surface Grinders.

These machines can also handle many parts at a time, which allows us to provide excellent pricing for large quantity runs. All of these machines produce high accuracy and are especially suited for grinding long steel bars – 4140, A36, HR Steel Bar, and tool steel bar.

 

Machines and Capacities

Our 36″ x 168″ Mattison Grinder 400-S has the capacity to produce ground parts up to 24″ tall.  Our second, unique, 48″ x 200″ Mattison 400-S Reciprocating Grinder has further been modified with a 415 HP motor and is fully capable of step grinding up to 240″, and in some cases 260″.  This motor allows us to add pressure while slowing down the feed rate which increases the efficiencies while preventing heat buildup and plate burning.

We produce surface ground parts to incredibly close tolerances. Many times we can reach ± .001 parallelism, ± .002 per foot flatness, and as normally requested, to within ± .001-.005 thickness. Our production grinders along with our qualified machine operators allow us to grind these surfaces for you right the first time.
